Senior Software Engineer (fullstack - Enterprise Foundations)

Senior Full Stack Engineer

We're looking for a Senior Full Stack Engineer with strong leadership skills to help shape and deliver world-class user experiences in our AI-powered healthcare products.

You'll be comfortable working across the stack, but have a particular interest in crafting elegant, intuitive, and performant interfaces. You combine technical depth with a product mindset — thinking not only about how features are built, but why they matter, and how they can best serve our users.

What you'll do:

• Lead development of foundational systems: We're looking for someone to lead the design and development of key systems such as authentication across all of Heidi's platforms; working closely with other teams and stakeholders to build systems that enable other teams and the product roadmap.
• Champion quality & maintainability: Design simple and maintainable systems to solve complex problems, author tests, optimise performance and create fault tolerant systems so teams can move fast without compromising quality.
• Continuously improve: Drive continuous improvement by providing technical leadership and mentorship, identifying process or development bottlenecks, and working with our AI enablement team to improve both the speed and safety with which we release.

What we will look for:

• 5+ years experience working on complex, high-scale, or highly integrated services, with the ability to work effectively on both frontend (TypeScript, React) and backend (Python or TypeScript) services. Experience with REST/GraphQL design, domain-driven architecture, relational and NoSQL datastores.
• Strong communication and collaboration skills, with the ability to work effectively in a cross functional team, balance priorities from other departments and coordinate the release of your team's features.
• Cloud proficiency (GCP or AWS): containers, CI/CD, infrastructure-as-code, observability and security best practices.
• A proven history of architecting and building highly available, scalable, secure & performant systems.
• A product mindset — you care deeply about solving real problems for users and measuring the impact of what you build.
• Bonus: Experience with authentication and identity platforms is a strong plus, especially with good understanding of security concerns and best practices across APIs, web and native/mobile.

What do we believe in?

• We create unconventional solutions to difficult problems and we build them fast.
• We want you to set impossible goals and make them happen, think landing a rocket but the medical version.
• You'll be surrounded by a world-class team of engineers, medicos and designers to do your best work, inspired by our shared beliefs:
• We will stop at nothing to improve patient care across the world.
• We design user experiences for joy and ship them fast.
• We make decisions in a flat hierarchy that prioritizes the truth over rank.
• We provide the resources for people to succeed and give them the freedom to do it.

Why you will flourish with us?

• Flexible hybrid working environment, with 3 days in the office.
• Additional paid day off for your birthday and wellness days
• Special corporate rates at Anytime Fitness in Melbourne, Sydney tbc.
• A generous personal development budget of $500 per annum
• Learn from some of the best engineers and creatives, joining a diverse team
• Become an owner, with shares (equity) in the company, if Heidi wins, we all win
• The rare chance to create a global impact as you immerse yourself in one of Australia's leading healthtech startups
• If you have an impact quickly, the opportunity to fast track your startup career!

Help us reimagine primary care and change the face of healthcare in Australia and then around the world.
